today I updated from MATE 1.4 to 1.6. Everything works as it should, except my custom keybindings.Apparently they haven't been migrated from mateconf to Gsettings.I tried the instructions http://community.linuxmint.com/tutorial/view/1171 but it didn't work.

In MateConf my keybindings were stored in /desktop/mate/keybindings/custom0.A new keybinding I created has been stored in Gsettings in /org/mate/desktop/keybindings/custom0
